I added to a prior post about spark plug heat ranges after finding dry fouling on my BR8ES plugs in all cylinders. (Compression is good, 76-78/80) I run an IO 320 B1A with dual LSE Plasma III and AFP injection with 9:1 pistons. I typically fly LOP. Klaus' manual recommends the Denso IK27 which is actually a cooler plug that the NGKs in there now (the 8 heat range corresponds to a 24 in the Denso world). I wrote Klaus but, no surprise, haven't heard back. Using the 27, or even 24 when already noting fouling with the current NGK doesn't add up to me. While looking and reading, I came upon the website for Brisk Racing. There are myriad plug types and one that I am not familiar with called a multi-spark plug.
The description is this: "they produce more than one spark per impulse of the ignition system. More than one simultaneous point of ignition results in better and more spontaneous ignition of the air-fuel mixture. Spark Plug sparks are not shielded by the ground electrode; therefore it provides faster, unrestricted expansion of the flame front. The mixture burns more uniformly and more quickly. The result of better utilization of available combustion energy is more power, better acceleration, lower harmful exhaust emission and reduction in fuel consumption."
It says it is designed for high output ignition systems. Would this be applicable to my set-up? Has anyone used or considered this brand or specific plug before? I do tend to overthink things so I apologize in advance. I am NOT an engineer but want to learn and understand these questions as they arise. It makes me safer and better able to make decisions that are beneficial to my aircraft and flight safety. I appreciate any knowledge from you all.
Thanks and be well everyone,
David
